tau (pSer416) antibody

Antigen: tau

Epitope: pSer416

Clonality: Polyclonal

Host: Rabbit

Reactivity: Rat (Rattus)

Application: Western Blotting (WB)

Catalog no.: ABIN361456

Additional Information

Alternative name: Phospho Ser416 Tau

Format: Affinity-purified

Description: Tau is a key microtubule-associated protein that plays an important role in the formation of microtubules in axons (Binder et al. 1985). Six tau isoforms have been identified as products of a single gene produced by alternative mRNA splicing (Goedert 1990). Tau mutations have been implicated in many neurodegenerative disorders such as Alzheimer’s disease (AD), Pick’s disease and progressive supranuclear palsy. It has been well documented that hyperphosphorylated tau is a major component of paired helical filaments in AD brain (Lee 1995). Serine 416 has been demonstrated to be a major phosphorylation site in vitro by CaM kinase II (Steiner at al. 1990). Anti-Phospho-Ser416 Tau Western blot of rat brain homogenate showing specific immunolabeling of the ~59, 65, 68k Tau isoforms phosphorylated at Ser416(control). Immunolabeling is blocked by preadsorption with the phospho-peptide used as antigen (Peptide) but not by the corresponding dephospho-peptide (not shown).

Specificity: Specific for ~59, 65, 68k tau protein phosphorylated at Ser416.

Application Details

Application Notes: Recommended Dilution: WB: 1:1000 Quality Control: Western blots performed on each lot.

Purification: Prepared from rabbit serum by affinity purification via sequential chromatography on phospho- and dephospho-peptide affinity columns.

Storage: Store at -20 °C, stable for 1 year

Restrictions: For Research Use only
